How are you using the Windows 2003 POP3 Server?

I saw a link on the “hellomate“ MS Exchange blog to a post singing the praises of the POP3 Server that comes in Windows Server 2003 and it reminded me that I wanted to write about this and ask people to comment or write, and tell me what you are using the POP3 server for,…

How are you using the Windows 2003 POP Server, Part II

In a previous post, I asked people how they are using the Win2K3 POP server and what features they wish it had.  One thing I’d like to get, especially from people who posted that they do use it today, is some more details on why and how they are using it.  1) It seems to…

Catchall vs Check recipients

We get two different common requests for features that we have solutions for, but it’s funny that they are incompatible.  I accidentally discovered this on my own Exchange 2003 server at home. Feature 1: “Catchall” mailbox The idea with this one is that you have people mailing you at info@company.com, sales@company.com, etc. and you don’t…

Configure Exchange 2003 to check recipients in SMTP protocol

For years, people have been asking me, “how can I make Exchange work just like sendmail, where it rejects invalid recipients during the SMTP protocol?”  Sendmail has historically not had a directory, and so checking if a recipient was valid was just a getpwnam() call, which is quick.  Of course, when Exchange accepts a user…

ResolveP2, RerouteViaStore, and its equivalent in Exchange 2003

Recently I have encounted a number of people who asked what the ResolveP2 reg key in Exchange 5.5 was meant for, and how to emulate it in Exchange 2003. — ResolveP2 in Exchange 5.5 ResolveP2 tells the Exchange server “when the server is storing MIME content, and needs to convert it to MAPI properties, does…

Sharing a domain between two Exchange orgs

Luke asks: I am in the process of migrating from Exchange 5.5 to Exchange 2003 for a company that has multiple small (less than 5 users) branch offices. They want to migrate slowly, so here’s my dilemma: The current Exchange 5.5 will still be active for a while. I’m using the Exchange Migration Wizard in…

Treo 650 and Exchange ActiveSync

I am sorely overdue in posting, and I apologize about that.  I will hide behind the sorry excuse that the vast majority of what I do nowadays is work on an upcoming release of Exchange that we aren’t talking about yet, so I feel like I can’t blog all that much about my current work. …

What’s the story with WINS?

Recently, someone asked the following question on an internal Microsoft distribution list: Can someone please outline the ways in which Exchange 2003 is dependant upon WINS..? Here’s the answer I wrote back: Exchange 2003 is dependent upon three different things that are related to WINS: 1) DNS resolution of “short names” – i.e. there are…
